It only happens on a Friday if it can't happen on the Saturday night of a long weekend. A bit like the dog getting sick or the horse getting caught in the fence.
One of my 'foobs' looks like a genuine, honest to goodness tit following rads; though it waited until I had finished treatment and was safely away from daily nursing help before it blew up. It seems mine is lymphoedema and I've got an appointment on Monday with she-who-deals-with-sloshy-knockers to learn how to massage it out. What a shitting nuisance.
If you feel unwell or unsafe try to get hold of some medical advice this weekend -out of hours GP would be a better experience than turning up at your local hospital if that is possible. I wouldn't get too vigorous with any treatment until you know what you are dealing with. Marg
